House alarm fault, help please.
As of the last few days our house alarm outside bell (siren really) box
sounds if the mains goes down. It never used to, the only reason I first noticed was an RCD tripping fault on a mains ring circuit tripped the fuse box RCD, and the alarm sounded, although the control panel was in "Daytime" mode, and no panel lights showed. Restoring mains stops the alarm, but resetting the alarm panel has no effect. Any clues what's up with the damned thing? Otherwise the system appears to function normally. We get not infrequent power outages here, so this could be a damned nuisance ;-) Thanks. -- Best Regards, Chris. |

Test to see if there is an output If no power gets to the bell (either mains or battery) then the siren will activate from it own second battery |

Test to see if there is an output I had _identical_ symptoms a few years ago and the cure was a new 12V rechargeable battery inside the alarm control panel. The old battery was still giving 12V (nominal) at the output terminals but it appeared not to supply enough current at the point where the mains failed and the alarm latched on. In my control panel the battery is connected with two spade terminals and was very easy to replace. The control panel will probably have a tamper switch which will set off the alarm as you remove the cover. If you remove the mains power AND the battery make sure that you still have the instructions (and understand them) about configuring alarm from scratch. The instructions that came with my alarm were in that classic Far East to English translation - with only half the information needed to program the box in the user guide and the other half in a separate installation guide)) Suitable batteries can be obtained from CPC, Maplin and many other places. http://custom1.farnell.com/cpc/produ...CPC+Catalogue& category%5Fname=Electrical%2C+Security+and+Test+%2 D+Batteries+%2D+Recharg eable+%2D+Lead+Acid+%2D+Alarm+Batteries&product%5F id=258210 -- Alan |

Sounds like your internal battery in the alarm panel is
flat/goosed/knackered. Simple to replace. Basically if the bell box doesn't have 12volts going to it, it will start to ring. And nothing will stop it unless its own battery is disabled or disconnected or power is restored. -- Regards SantaUK Mail me at: arjf (ng) zzvyyne (qbg) pb (qbg) hx === ROT13 Use http://andrewu.co.uk/tools/rot13/ to convert to readable format "Chris Wilson" wrote in message ...

Has anybody ever noticed any action being taken as a result of an activated house alarm. Have you ever seen the police screeching to a halt outside the premises? Do you phone 999 when you hear an alarm? In my opinion, these things are nothing but an annoyance and a complete waste of time and think most potential burglars realise this. Terry D. |

I disagree with you In our cul de sac, no one has a dodgy alarm If one sounds we know it's worth looking into The Police have responded to just an audible alarm, as they were nearby The 'night set' mode gives us real peace of mind, knowing we won't sleep through any burglaries Regarding the burglars, there are so many homes without any security, you average (junkie) thief will target those, leaving alarmed homes alone I also had the same problem as the OP and this was cured by a new battery which I bought from City Electrical Factors for about £10 Regards Hays T610 Housings in stock now!! www.phonepro.go.to --- Outgoing mail is certified Virus Free.

I have a new house and it is wired up ready to take an alarm and I am seriously considering it. Having said that I remember watching a documentary a few years ago that interviewed burglars and they basically fell into 2 camps. First was the opportunist (usually a drug addict) who takes a few chances as they can and an alarm would put them off. The second was the "professional burglar" who is skilled at breaking into houses and knows exactly what is worth money. They said that a burglar alarm is actually an attraction as they believe there is something worth stealing and they said that most people ignore them so they are not very high risk. Both said they would never do a house with a dog. I think I will probably get an alarm as most burglaries are done by druggies these days, but I also have all my lights on timers so anyone watching would never know if I was out or in. Angela |

As of the last few days our house alarm outside bell (siren really) box
sounds if the mains goes down. Most alarms have a battery backup in the panel - it could be the battery is now duff (they do fail after a few years). Its been a while since I last fitted one, but the most common brand was Yuasa IIRC... -- Please add "[newsgroup]" in the subject of any personal replies via email * old email address "btiruseless" abandoned due to worm-generated spam * --- My new email address has "ngspamtrap" & @btinternet.com in it ;-) --- |
